How to use an earlier version of ruby 1.9.2
I am using rvm and when I installed ruby 1.9.2 it installed ruby-1.9.2-p290 and a few days ago I was unable to link to the older one but asked to install ruby-1.9. 2-P318.
Is it necessary to upgrade to a newer version or could we instruct rvm to use the gemset created with the older version.
All teams RVM, such as rvm install
and rvm use
, can have the patch level, for example rvm install ruby-1.9.2-p290
. If you do not specify one, the last available patch level will be used.
As brandon said, you can also customize the default ruby version with the -default flag. This will ensure that you are using the same version every time you start your terminal.
rvm use ruby-1.9.2-p290 --default
You can also customize the .rvmrc file in the directory you are working in to ensure that other developers are using the same ruby version and patch level as you.
touch .rvmrc && echo "rvm use ruby-1.9.2-p290" >> .rvmrc
